21. The warp threads are tensioned by a spring. 22. The office floors are formed from post-tensioned band beams supporting conventional reinforced slabs. 23. Also crossing the International Gateway are two other single-span post-tensioned bridges. 24. A rolamite is a mechanical device, consisting of a roller suspended within a tensioned band. 25. The Daisy system uses tensioned torsion transfer of kite motion to turn a ground based generator. 26. Tensioned kates have a band that loops over the bobbins to prevent them from spinning freely.27. The post-tensioned flat plates of the upper floors are concrete and measure in thickness. 28. This system is similar to the partially tensioned striker found in the Glock series of pistols. 29. The building's glass facade wraps the structure of the building like a tensioned membrane. 30. The perimeter of the building has columns spaced apart and supporting post-tensioned edge beams.
